Hybrid component and associated production method

Abstract

The present invention relates to a hybrid component comprising a sheet-metal metal body and a plastic body injection-molded onto the sheet-metal body. The sheet-metal body is produced by cutting, edging, stamping and/or plastic forming a plate-shaped metal sheet, and has a surface coating on at least one visible side, as well as at least one uncoated cut or stamped edge. The plastic body is injection-molded so that it seals the at least one uncoated or stamped edge of the sheet metal body and stiffens the sheet metal body.

1 . A hybrid component comprising a metal body and a plastic body injection-molded onto the metal body, wherein: 
 the metal body is a sheet metal body formed by one of edging, stamping, plastic forming and cutting a plate-shaped metal sheet provided with a surface coating on at least one visible side thereof;    the metal body has at least one uncoated edge, and    the plastic body is adapted to stiffen the sheet metal body and seal the at least one uncoated edge.    
   
   
       2 . The hybrid component as claimed in  claim 1 , wherein the sheet metal body is produced from a coil—of coated metal sheet.  
   
   
       3 . The hybrid component as claimed in  claim 1 , wherein, in a region of the uncoated edges of the sheet metal body, the plastic body comprises a plastic other than that in the remaining body.  
   
   
       4 . The hybrid component as claimed in  claim 3 , wherein the plastic body is one of a single-component part and a two-component part.  
   
   
       5 . The hybrid component as claimed in  claim 1  wherein the plastic body completely covers a visible side of the sheet metal body.  
   
   
       6 . A method for the production of a hybrid component comprising a sheet metal body and a plastic body, the method comprising: 
 forming a sheet metal body by one of edging, stamping, plastic forming and cutting a plate-shaped metal sheet provided with a surface coating on at least one visible side, whereby at least one uncoated cut edges is formed on the sheet metal body,    injection molding a plastic body onto the sheet metal body such that the plastic body stiffens the sheet metal body and seals the at least one uncoated edges.    
   
   
       7 . The method as claimed in  claim 6 , wherein the sheet metal body is produced from a coil—of coated metal sheet.  
   
   
       8 . The method as claimed in  claim 6 , wherein: 
 the plastic body is injection-molded onto the sheet metal body by means of a two-component technology; and    in a region of uncoated edges of the sheet metal body, the plastic body comprises a plastic which differs from that in the remaining body.    
   
   
       9 . The method as claimed in  claim 8 , wherein the injection molding of the plastic body by the two-component technology is carried out in a single injection-molding die.  
   
   
       10 . The method as claimed in  claim 6 , wherein the plastic body is injection-molded onto the sheet metal body such that it completely covers a visible side of the sheet metal body.  
   
   
       11 . A hybrid component comprising: 
 a sheet metal body formed from a plate-shaped metal sheet using a forming process selected from the group consisting of edging, stamping, plastic forming and cutting;    a surface coating formed on at least one visible side of said sheet metal body, said surface coating covering said at least one visible side, except for at least one uncoated edge formed during said forming process; and    a plastic body injection-molded onto the sheet metal body;    wherein the plastic body is adapted to stiffen the sheet metal body and seals the at least one uncoated edge.    
   
   
       12 . A method of making a hybrid component comprising a sheet metal body and a plastic body, the method comprising: 
 providing a plate-shaped metal sheet having a surface coating on at least one visible side thereof;    forming a sheet metal body having at least one uncoated cut or stamped edge by one of edging, stamping, plastic forming and cutting the plate-shaped metal sheet; and    forming a plastic body by injection molding a plastic material onto the sheet metal body;    wherein the plastic body is adapted to stiffen the sheet metal body, and seals the at least one uncoated cut or stamped edge.
